![]() This example code is in the public domain. It is only to mount the ultrasonic module onto for a sonar style project which makes the small size ideal. The other lead is the control lead and this is usually orange or yellow. The color of the leads varies between servo motors, but the red lead is always 5V and GND will either be black or brown. I would be interested in any fixes or knowledge on why it does this. For this experiment, the only thing connected to the Arduino is the servo motor. It does this very well and is a work-around for the 0-10 problem blind spot. If it is told to go between 0-10 it will keep rotating.Īs a work-around I have programmed it to sweep from 10 degrees as a start position to 190 degrees and return. It works for all angles except 0-10 degrees. ![]() I have programmed the servo to go to specific degrees and stay there. I don't think it is a power issue, but may be a pulse width driving issue causing an overshoot in one direction, or a problem with the servo finding the datum position. Then reverses and travels 260 degrees clockwise past the original start position at a slow pace, then accelerates to full speed round to the start position (approx 280 degrees) still clockwise. The servo goes at full speed to a start position, then rotates anticlockwise exactly 180 degrees at a slower pace as it should. The servo performed exactly the same as it did previously. I then used a LM7805 regulator with cap on the output connected to a 14v tool battery to supply the servo, and commoned the ground to the Arduino. The ground wire is typically black or brown and should be connected to a ground pin on the board. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. I originally tested it directly connected to the Arduino Uno as per the tutorials but found this is a bad idea and causes problems. Arduino Board Servo Motor 10k ohm potentiometer hook-up wires Circuit Servo motors have three wires: power, ground, and signal. I have a problem driving a new SG90 servo with the standard sweep sketch included in the examples. Hello, and thanks for previous help on this forum.
